Kewl Tune Deck #754229 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Toolbox
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 9 violation(s).

Identity & game plan

• Win condition: Synchro boss monsters from the Kewl Tune chain (Kewl Tune B2B, Kewl Tune Remix, Visas Amritara, Zalen) built from the Kewl Tune Tuner and non-Tuner engine; Mulcharmy and Nibiru card-advantage and hand-trap-driven board control with Fusion or Link finishers
• Turn 1 (going first): Normal Summon Kewl Tune Cue or Kewl Tune Reco, search a Kewl Tune card or a Synchro Spell (Kewl Tune Synchro, Duelist Genesis), then Synchro Summon a boss through the Kewl Tune Tuner chain
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Effect Veiler, Droll & Lock Bird and Ghost Ogre & Snow Rabbit to stop the opponent's first engine, then rebuild a Synchro board from the GY through Kewl Tune Mix and Kewl Tune Reco
• Recovery: Mulcharmy Fuwalos and Purulia draw cards once the hand is empty, and Kewl Tune Reco or Kewl Tune Mix recover a Tuner from the GY
• After siding: Not assessable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

The deck's engine is coherent: 24 exact-name Kewl Tune copies (34.3% purity) and a 25-card archetype core that is 95.9% likely to have at least one piece in a 5-card opening hand. Its Synchro and Tuner chain reaches several boss monsters (Kewl Tune B2B, Remix, Visas Amritara, Zalen), and 15 hand traps and about 20 removal or negation texts give it real interaction density, which is where most of the structural score comes from. The score is capped low because the list is Illegal: nine cards exceed their copy limits and three Forbidden cards are run (Kewl Tune Rotary, Called by the Grave, Anti-Spell Fragrance), so this is a theoretical, structural-only read. No recorded boards, guides or tournament data exist, so the combo ceiling and median are inferred from card text rather than measured. The score was built from consistency, interaction and conversion on the system as a whole, not from averaging card scores and not from the archetype's popularity.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12); illegal list cap (-10); no side deck (0). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 52.6, then -12 banlist modifier = 40.6, then capped at 30 because the deck is Illegal (theoretical/structural-only read)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · key two-card combo ≈ — · full-brick estimate ≈ 0.04 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Compact archetype core with a 0.959 chance of at least one core card in a 5-card opening hand
• Layered interaction: 15 hand traps plus removal and negation text on Synchro bosses
• Recursion through Kewl Tune Reco and Mix gives some route redundancy after disruption
• Synchro boss coverage from Extra Deck (B2B, Remix, Visas Amritara, Zalen, Loudness War)

Weaknesses

• Illegal list: 9 cards over copy limits and 3 Forbidden cards run
• Only 34.3% of the main deck is exact-name Kewl Tune; the engine relies on 33 generic and sub-archetype cards
• No recorded boards, so the combo ceiling and median are unmeasured
• No Side Deck, so there is no post-side adaptation
• High complexity: multi-step Synchro chains and several once-per-turn effects

Critical choke points

• The Kewl Tune Tuner chain depends on Kewl Tune Cue, Reco and Synchro, which are all over their legal copy limits
• Forbidden Kewl Tune Rotary removes the Tuner-search route, so the opening plan must rely on Reco and Mix alone

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, with 9 copy-limit violations and 3 Forbidden cards (verified from the banlist fields); Main 55, Extra 15, Side 0 against size rules 40-60 / 0-15 / 0-15 (verified); Archetype purity 34.3% (24 of 70 Main and Extra copies; verified count); Archetype core group P(>=1 in hand of 5) = 0.959 (verified hypergeometric output)
• Observed: Usage statistics: 10 of 25 core cards present in this list (verified inclusion data)
• Inferred: Engine consistency and brick rate from hypergeometric draws and card text; Combo ceiling and median from card text, since no recorded boards exist; Interaction density from role-hint tags on hand traps, removal and negation text
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (D13) with no tournament link
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry for going-first/second, matchup, brick or OTK rates Meta Power is Provisional unless a dated metagame sample is supplied Deck has no Side Deck, so post-side evaluation is not possible
